Type I restriction enzymes cut DNA at random locations far from their recognition sequence, type II cut within or close to their recognition sequence, type III cut outside of their recognition ...

“As soon as the Type II restriction enzymes were discovered—and HindII in particular—it was obvious that you could take a fairly large DNA and cut it into smaller pieces. And that offered you the ...

[65] Type II restriction enzymes cut DNA at specific recognition motifs and are therefore widely used as molecular biology tools. The presence of restriction-modification systems limits the ...

while HindII and HindIII are type II enzymes. As originally postulated by Arber, all restriction enzymes serve the purpose of defense against invading viruses. Bacteria protect their DNA by ...
